The DOM Inspector extension does not appear to be working in T/Bird 58b. There are also no chrome inspecting 'Web Dev' tools in T/Bird 58b, as there are in Firefox (poor, as they may be).

As can be imagined, the two together make it pretty difficult to develop extensions and themes for Thunderbird. If you're dropping that side then say so and we can all go home, if not, a working DOM Inspector would be good to have.
